Spillover Losses in Small Cassegrain Antennas

Abstract

In this study, first the radiation properties of a small Cassegrain antenna for 10λ were examined. Next the source of spillover is discussed, and parametric curves showing losses as a function of the Cassegrain design parameters are presented. These results lead to some useful relationships for choosing the design parameters for optimum gain performance.
